Testing Models Relating Rejection, Depression, Interpersonal Needs, and Psychache to Suicide Risk in Nonclinical Individuals

Objectives: Using structural equation modeling, we tested a primary model of suicide risk and 3 competing, alternative models based on 4 psychological variables deemed important in the literature (perception of parental rejection, depression, interpersonal needs comprising perceived burdensomeness and thwarted belongingness, and psychache), in a nonclinical sample of Portuguese adults. Method: A convenience sample of 203 adults (100men, 103women; aged18–65 years) participated in this study. Results: Analyses demonstrated that the proposed primary model had the best fit to the observed data. The differences in fit indexes for this model and one of the alternative models, however, were not substantial. Conclusion: Perceived parental rejection related directly to suicide risk and indirectly via depression and interpersonal needs. Depression linked indirectly to suicide risk via interpersonal needs and psychache. Interpersonal needs related directly to suicide risk and indirectly via psychache, which related directly to suicide risk

Suicide risk in a Portuguese non-clinical sample of adults

Background and Objectives: This exploratory study simultaneously tests the contribution of socio-demographic, clinical, distress, and personality variables for identifying suicide risk in a non-clinical sample. Methods: A convenience sample of 810 adults ranging in age from 19 to 67 years (M = 36.34, SD = 12.46) and living in various Portuguese regions participated. Their education varied from 6 to 21 years of schooling (M = 11.74, SD = 5.14). Participants responded to sociodemographic questions, the Depressive Experiences Questionnaire, the Center for the Epidemiological Studies of Depression Scale, and the Suicide Behaviors Questionnaire-Revised. Results: In the present sample, 4.3% of participants indicated past suicide attempts, 27.9% reported some lifetime suicide ideation, and 6.4% indicated a past suicide plan. Depressive symptoms, having seen a psychologist or psychiatrist, self-criticism, and education discriminated between participants who had attempted suicide (n = 35) and those who had not attempted to die by suicide (n = 775). Depressive symptoms, having seen a psychologist or psychiatrist, self-criticism, psychiatric disease and age discriminated between participants who scored below (n = 650) and who scored equal to or above (n = 160) the cut-off score for the Suicide Behaviors Questionnaire-Revised. Conclusions: Results have implications for the assessment of suicide risk

IAT faking indices revisited : Aspects of replicability and differential validity

Research demonstrates that IATs are fakeable. Several indices [either slowing down or speeding up, and increasing errors or reducing errors in congruent and incongruent blocks; Combined Task Slowing (CTS); Ratio 150–10000] have been developed to detect faking. Findings on these are inconclusive, but previous studies have used small samples, suggesting they were statistically underpowered. Further, the stability of the results, the unique predictivity of the indices, the advantage of combining indices, and the dependency on how faking success is computed have yet to be examined. Therefore, we reanalyzed a large data set (N = 750) of fakers and non-fakers who completed an extraversion IAT. Results showed that faking strategies depend on the direction of faking. It was possible to detect faking of low scores due to slowing down on the congruent block, and somewhat less with CTS—both strategies led to faking success. In contrast, the strategy of increasing errors on the congruent block was observed but was not successful in altering the IAT effect in the desired direction. Fakers of high scores could be detected due to slowing down on the incongruent block, increasing errors on the incongruent block, and with CTS—all three strategies led to faking success. The results proved stable in subsamples and generally across different computations of faking success. Using regression analyses and machine learning, increasing errors had the strongest impact on the classification. Apparently, fakers use various goal-dependent strategies and not all are successful. To detect faking, we recommend combining indices depending on the context (and examining convergence)

Assessing psychache as a suicide risk variable: Data with the Portuguese version of the psychache scale

Several studies have consistently related psychological pain to suicide risk. Psychache, according to Shneidman's perspective and measured by the Psychache Scale has been confirmed as an important variable in risk prediction. In the present study, we evaluated psychache as a construct related to suicide risk using data obtained with the Portuguese version of the Psychache Scale translated from the original English version. A community sample of 628 individuals responded to the Portuguese version of the Psychache Scale, the Suicidal Behavior Questionnaire-Revised, the CES-D Scale, the Beck Hopelessness Scale, and the Suicide Ideation Questionnaire. Results supported the unidimensional scoring of the Psychache scale, its ability to differentiate between individuals at-risk for suicide from individuals not at-risk, its relationship with different, but related, constructs and its ability to predict suicide ideation

Portuguese Version of the Suicidal Behaviors Questionnaire-Revised: Validation Data and the Establishment of a Cut-Score for Screening Purposes

The aim of the present study is to provide validation data regarding the Portuguese version of the Suicidal Behaviors Questionnaire Revised in nonclinical individuals. Two studies were undertaken with two different nonclinical samples in order to demonstrate reliability, concurrent, predictive, and construct validity, and in order to establish an appropriate cut-score for nonclinical individuals. A sample of 810 community adults participated in Study 1. Results from this study provided information regarding scale internal consistency, exploratory and confirmatory factor analysis, and concurrent validity. Receiver operating characteristic curve analysis established a cut-off score to be used for screening purposes with nonclinical individuals. A sample of 440 young adults participated in Study 2, which demonstrated scale score internal consistency and 5-month predictive validity. Further, 5-month test-retest reliability was also evaluated and the correlations of SBQ-R scale scores with two other measures that assess constructs related to suicidality, depression and psychache, were also performed. In addition, confirmatory factor analysis was undertaken to demonstrate the robustness of the result obtained in Study 1. Overall, findings supported the psychometric appropriateness of the Portuguese Suicidal Behaviors Questionnaire-Revis

Self-criticism, intensity of perceived negative life events, and distress: Results from a two-wave study

The aim of the present study was to evaluate whether changes in the maladaptive personality trait of selfcriticism and changes in the interaction between this trait and the intensity of perceived negative life events predict changes in distress over a period of five months. A final sample of 207 young adults participated, responding to the Depressive Experiences Questionnaire, the Life Experiences Survey, and the Brief Symptom Inventory. Results demonstrated that changes in self-criticism predicted changes in distress over and beyond the prediction associated with assessing the intensity of perceived negative life events. Further, changes in selfcriticism and perceived negative life events interacted in the prediction of changes in distress. Findings are discussed in terms of personality characteristics of self-critical individuals and of the construct of resilience

Parental Rejection, Personality, and Depression in the Prediction of Suicidality in a Sample of Nonclinical Young Adults

This study tested a prediction model of suicidality in a sample of young adults. Predictor variables included perceived parental rejection, self-criticism, neediness, and depression. Participants (N 5 165) responded to the Depressive Experiences Questionnaire,theInventoryforAssessingMemoriesofParentalRearingBehavior, theCenterforEpidemiologicalStudiesDepressionScale,andtheSuicideBehaviors Questionnaire—Revised. Perceived parental rejection, personality, and depression wereassessedinitiallyatTime1,anddepressionagainandsuicidalitywereassessed 5 months later at Time 2. The proposed structural equation model fit the observed data well in a sample of young adults. Parental rejection demonstrated direct and indirect relationships with suicidality, and self-criticism and neediness each had indirect associations with suicidality. Depression was directly related to suicidality. Implications for clinical practice are discussed

Psychological impact of the COVID-19 pandemic and suicide ideation in community adults in Portugal: preliminary data

BACKGROUND: The aim of the present study was to evaluate the perceived impact of the COVID-19 pandemic state of emergency in Portugal and the contribution of several socio-demographic and clinical variables, including having had a psychiatric diagnosis, on suicide ideation. Further, we tested whether the perceived impact of the pandemic mediated the association between having had a psychiatric diagnosis and suicide ideation. METHODS: A sample of 227 Portuguese community adults (183 women, 44 men) participated online. RESULTS: Low education, having had a psychiatric diagnosis, and the perceived psychological impact of the pandemic each related to the presence of suicide ideation. Perceived psychological impact partially mediated the association between having had a psychiatric diagnosis and suicide ideation, as indexed by the total score on the Suicide Ideation Scale. CONCLUSIONS: Individuals with a psychiatric diagnosis, with a lower education level, and with a perceived psychological impact of the pandemic are at greater risk for experiencing suicide ideation, and psychological impact appears to be stronger for persons with a psychiatric diagnosis and, thus, resulting in more suicide ideation. A potential limitation was the use of only three items for assessing the impact of the pandemic
